Heater core was replaced and even setting dial to a/c/cold, hot air blows from the vents. There is an issue with the A/C not working too, which i have not had diagnosed yet.

    Broken Temperature Blend Air Door(s), improper heater replacement-door jammed & stuck in heat position, bad Actuator or unplugged, no refrigerant put back into AC after repair of heater. These are probably the most likely-any one & possibly multiple combinations.
